摘要： A transmitter comprises a power amplifier (PA) with a power supply input (PI) and an output (PAO) to supply a transmission signal (Vo) with an output power (Po). A power supply (PS) has power supply outputs (PSO1, PSO2) to supply a first power supply voltage (PV1) with a first level and a second power supply voltage (PV2) with a second level, higher than the first level. A switching circuit (SC) is arranged between the power supply outputs (PSOI, PSQ2) and the power supply input (PI) to supply a selected one of the first power supply voltage (PV1) or the second power supply voltage (PV2) to the power amplifier (PA). A controller (CO) supplies a control signal to the switching circuit (SC) in response to a first power change command (PC) indicating a first desired level of the output power (Po), to supply the first power supply voltage (PV1) to the power supply input (PI). The controller (CO) supplies the control signal to the switching circuit (SC) in response to a second power change command (PC) indicating a second desired level of t:1e output power (Po) and succeeding the first power change command (PC), to supply either the first power supply voltage (PV1) or the second power supply voltage (PV2) to the amplifier power supply input (PI) depending on values of said first desired level and said second desired level. The controller (CO) controls the power supply (PS) to vary a level of at least one of the power supply voltages (PV, PV2) to always have available one of the power supply voltages with a level suitable for increasing the output power (P0) substantially instantaneously.

摘要： The present invention relates to an all n-type transistor current mirror for mirroring an input current to an output current. The current mirror comprises an input n-type transistor (T4, QO, T1) interposed between a positive supply plane (VCC) and an input node (104, 202, 310) with its collector being connected to the positive supply plane (VCC) and its emitter being connected to the input node (104, 202, 310). An output n-type transistor (T3, Q1, T2) is interposed between the positive supply plane (VCC) and an output node (106, 204, 314) with its collector being connected to the positive supply plane (VCC) and its emitter being connected to the output node (106, 204, 314). A feedback circuit equals base-emitter voltages of the input (T4, QO, T1) and the output transistor (T3, Q1, T2) in order to mirror the emitter current of the input transistor (T4, QO, T1) to the emitter current of the output transistor (T3, Q1, T2). The all n-type transistor current mirror is highly advantageous by overcoming the shortcomings of technologies such as MOBI3, GaAs, and InP of being unable to provide p-type transistors.

The amplifier according to the invention further includes a third and a fourth transistor T3 and T4 which form a differential pair; degenerated by means of a degenerating impedance Req which has a nominal value equal to that of the load impedance RL of the amplifier, which differential pair (T3, T4) is intended to be controlled by means of a control signal (−Vin/2, Vin/2), in anti-phase with the input signal (Vin, −Vin). The invention permits to double the output current Iout of the amplifier without, however, increasing its power consumption.
